OBJECTIVES To assess whether plate bending at a hole significantly changes the biomechanical properties of a locked screw. METHODS Coronal plane bends of 5-, 15-, or 45-degree angles were placed in 3.5-mm locking compression plates with the apex at a locking hole. An additional 45-degree angle test group was created in which a threaded screw head insert was placed before bending. Ten plates w...

in this paper a discrete big bang-big crunch algorithm is applied to optimal design of reinforced concrete planar frames under the gravity and lateral loads. optimization is based on aci 318-08 code. columns are assumed to resist axial loads and bending moments, while beams resist only bending moments. second-order effects are also considered for the compression members, and columns are checked...

An electrostatically driven micromirror is described. The vertical comb of a three-dimensional microstructure is realized by bending the device wafer having microstructures. By resetting the bending angle, the tuning of the vertical gap between moving and stationary combs is possible. The characteristics of the vertical comb drive actuator can be tuned, confirming the performance. key words: mi...

Recent developments in the study of the laser bending process are reviewed and presented to obtain new perspectives along the lines of dimensional characteristics and mechanical properties of the formed parts. Both numerical and experimental results are described and compared. The dimensional characteristics examined include bending angle variation and bending edge curving. The mechanical prope...

  Background: There are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. In the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. Methods: Forty patients with valgus knee malalignment were randomly assigned to two equal nu...

The marine derrick sometimes operates under extreme weather conditions, especially wind; therefore, the buckling analysis of components in is one critical contents engineering safety research. This paper aimed to study local stability and propose an analytical method for geometrically nonlinear problems. rod simplified as a compression with simply supported ends, which subjected transverse unif...

Most anuran larvae show large lateral oscillations at both the tip of the tail and the snout while swimming in a straight line. Although the lateral deflections at the snout have long been considered an inefficient aspect of tadpole locomotion, a recent hydrodynamic model suggests that they may in fact help generate thrust. It is not clear though exactly where this bending takes place. The vert...

Out-of-plane and in-plane free vibrations of angle-ply and cross-ply laminated composite beams with different boundary conditions are studied. The effect of fiber angle on out-of-plane bending, torsional, in-plane bending, and axial natural frequencies are investigated separately. The beam is modeled and analyzed by the finite element method (FEM). The finite element software package ANSYS is u...

Unlike mammals, whose development is limited to a short temporal window, plants produce organs de novo throughout their lifetime in order to adapt their architecture to the prevailing environmental conditions. The production of lateral roots represents one example of such postembryonic organogenesis. An endogenous developmental program likely imposes an ordered arrangement on the position of ne...

The liquefaction of soil surrounding a pile significantly affects the dynamic interaction between and pile. In particular, sloping ground can induce permanent deformation bending moment on due to lateral displacement liquefied in downslope direction. However, numerical analysis studies piles installed liquefiable slope have been very limited not properly simulated behavior Therefore, modified s...
